Ambulatory Leg

My design for the ambulatory leg is meant for low to medium levels of activity with minimal amounts of stress on the leg itself. Each leg is tailor-made to the user, with a rendered 3D model of their opposite leg made. This is used for a titanium 3D printing of the prosthetic leg. Only a 1/4" outer shell would be printed to maximize strength while minimizing weight. The model would also be scaled down in terms of width and length to do the same. The leg has a connecting rod that is attached to the knee joint to provide the mobility discussed in the "System" page of this site.

Ambulatory Foot

My ambulatory foot design is specified for walking and general everyday activity. It is constructed of two sheets of 1/4" carbon fiber, shaped to absorb any stress that may be placed upon the leg or joints. The toe and heel also bend upwards so any obstructions on the ground won't cause the user to trip. The stainless steel rod that connects the foot to the leg is encased in formed stainless steel. The support towards the back of the foot provides stability and towards the bend in the bottom carbon fiber sheet, which allows for more load absorption.

Precision Control Foot

My precision control foot design was focused on activities with very little stress placed upon the leg. Its main purpose is for uses that require control of the ankle and the foot. For example, it may be used to drive or to play the drums. It is again made of a 1/4" carbon fiber sheet with stainless steel supports to connect to the ankle joint. The data processed by the circuitboards in the knee joint is sent through wires encased in rubber tubing in the leg. Once the signals reach the ankle joint, they tell the joint how to move. Just like the knee joint, it moves both on the x-axis and the y-axis. However, it has far less movement range than the knee joint, just as a real ankle would have.
